I have just returned to Rocket German after a break of a few months and what a change for the better. As far as I can tell everything in both the Android app and the Windows version now functions flawlessly. I can take advantage of all the features and learning German with Rocket Languages has become a pleasure again. Rocket German is definitely my language learning programme of choice.
It really works too. I am currently visting Germany and can understand most of what is said. More surprisingly Germans even seem to understand me, which has not always been the case in the past. In fact I am so pleased that I am seriously considering trying the French version to see if it will help me brush up my very rusty French.
